    To remove the crankshaft pulley on my SBC 305, there are 3 bolts in a triangular pattern and 1 in the center. I was thinking the one in the center would not have to be removed, but now I am thinking I must be wrong. What is the best way to keep the crank from turning while removing that middle bolt? I have the other 3 bolts off right now, nowhere to hold to secure the crank while I loosen the middle one. My crank pulley split clean through on me, never heard of that happening before.

    You can use a tool on the flyweel...or just take the bolt out and move the engine back to where it was with a flywheel tool.... i have used a pair of vice grips to turn the motor....

    I'm inclined to use the impact on the center one, but I'll presume you don't have one handy.

    Also helps if your motor is seizes so the crank can't turn :doah:

    In your case, try something like this:

    Harbor Freight sells a cheaper one -- that was just the first Google hit I found.

    Put the bike chain around the pulley, and you'll get a LOT of leverage. Put a cheater pipe pn the pliers and you'll have plenty.

    Don't ask me why I know this :whistle:

    Put the belt back on if you can, it usually will hold it enough to pull the bolt.

    Put a long breaker bar on it, and turn the engine with the starter...:rolleyes:

    sheesh, what's wrong with you guys, the easiest way to do something, and you want to tell him to get the proper tools for the job, especially something as simple as removing a balancer, basic mechanical stuff here.




































    :D :haha: :doah: :wink1: :p:

    That wasn't as bad as I was anticipating. Used a strap wrench on the pulley and came right off.
